Disks with an abrasive layer of resin-bonded or metal-bonded diamond grains are used to process ceramic surfaces because of their excellent cutting quality, their low rates of wear, and the ability of diamond to hold its edge. Disks with a synthetic resin bond are suitable for hard materials, such as silicon nitride ceramics and sialon ceramics. Metal-bonded grinding disks are used for oxide ceramics and silicate ceramics. The type of bond on the disk helps determine the surface quality of the polished section.

A mirror surface was achieved on silicon nitride materials when ELID grinding was performed using a 4000 grit-size wheel. The finish ELID technology will find wide application in the optical and semiconductor industries such as mirror finishing of silicon wafers, many kinds of ceramics, ferrite, and glass. 

The objectives of this chapter are to determine the parameters of a new technology for high productivity, low cost of hot-pressed silicon nitride (HPSN) ceramic materials and to determine if an available grinding wheel system can be used for these applications.

Silicon carbide and alumina still dominate the abrasive industry at the present time. However their performance in the grinding of superalloys, ceramics, reinforced plastics, and other hard materials is generally unsatisfactory. This has led to the development of new abrasives such as synthetic diamond and cubic boron nitride. Cubic boron nitride was first synthesized in 1957 and has been available commercially since the 1970 s. Although not as hard as diamond, c-BN does not react with carbide formers such as Fe, Co. Ni, Al, Ta, and B at 1000 (while diamond does). However, it reacts with aluminum at 1050°C, with Fe and Ni alloys containing Al above 12S0"C, and with water and water-soluble oils.1 1...
